TWISTING AND COP-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 492,211, dated February21, 1893.

Application filed April 20. 1892. Serial No, 429,880- (No model.)

To all whom it may conceive.-

Be it known that 1, CHARLES C. KLEIN, a citizen of the United States,and a resident of Abington township, Montgomery county,

Pennsylvania, have invented certain Improvements in Twisting andCop-finding Machines, of which the following is a specification.

My invention relates mainly to a cop winding machine in which two ormore strands of yarn are twisted together at the same time that they arebeing wound into the form of a cop, although certain features of theinvention are applicable to cop winding machines generally.

The invention comprises certain combinations of parts fully set forthand specifically claimed hereinafter, hence detailed reference theretowill be unnecessaryin this part of the specification.

In the accompanying drawings: Figure 1, is a side view of a combinedtwisting and cop winding machine embodying my invention; Fig. 2, is aplan view of the same; and Figs. 3 to 12 are detached views illustratingfeatures of the invention or special details in the construction ofdifferent parts of the machine.

A represents one of the end frames of the machine to suitable hearingsin which are adapted the three shafts a, b and cl. The shaft 0!, is thedriving shaft, and is rotated from any suitable source of power, spur orother connecting gearing, such for instance as represented in Fig. 1,connecting the shafts a and b. 011 said shaft 7) is a pulley b whichreceives a belt b the latter being also adapted to a pulley d on theshaft d. 7 On the shaft a is a pulley a which receives a belt a fordriving a pulley a on a shaftf which is free to turn in a suitablebearing f on a swinging frame A the latter being hung to a rod g whichis mounted in lugs g projecting upward from one of the top bars of thefixed frame of the machine. The shaftfcarries one end of a flier B, ahollow shaft f at the opposite end of the latter being adapted to abearing f also mounted upon the pivoted frame A. The flier B is conicalin form at that end which is connected to the shaft f, said conical endof the flier constituting a bearing B of the desired form for the noseof the cop which is to be wound. (See dotted lines Fig. 2.)

Loosely mounted upon the shaft f and free to slide to and fro thereon isthe grooved hub of a traverse guide D having two arms 6 which are guidedat their forward. ends on the flier, said traverse guide having asuitable roller or eye 6' around which the strands of yarn pass beforereaching the cop. The to and fro motion of the traverse guide D iseffected by a crank d on the shaft cl, this crank acting through themedium of a connecting rod d upon an arm d which is slotted to embrace arock shaft (1 the latter having another arm d connected by a link d to aslide d free to move to and fro upon the pivot rod g and engaging with aslide 01* hung upon said rod and having an arm 01 which embraces theforked hub of the trav rse guide.

Secured to the rock shaft 02 is a slotted segment (1 the slot receivinga bolt (Z which also passes through the slot in the arm d so that bythis means provision is made both. for the longitudinal adjustment ofthe arm 61 to vary the length of stroke of the traverse guide, and alsofor circumferential adjustment of the rock shaft to determine thepositions assumed by'tlie guide when at the limit of its movements. 7

The shaftfis hollow and receives an internal shaft c which is driven ata speed somewhat greater or somewhat less than that of the shaft f, thisdifference in speed being effected in any desired manner, forinstance,in the machine shown in Figs. 1 and 2, it is effected by means of aseries of change gears 1, 2, 3 and 4, as shown in the diagram Fig. 4,the gear 1 being carried by the shaft f, the gears 2 and 3 by a shortcountershaft and the gear 4; by the internal shaft 2, so that byproperly proportioning the diameter of the Wheels the said internalshaft t' can be driven at any desired rate of speed in respect to thatof the shaft f. The forward end of the shaft 2' terminates in a pair ofspring fingers 2" which, when the winding is first started, engage witha cone it free to slide on a skewer 'm one end of which is mounted in arecess in the end of the shaft 0;, while its other end is mounted in acollar "m free to turn in a swinging head. m whichis pivoted to theflier B near the outer end of the same, said collar m having a cam m forengagement with a cam m on the swinging head m in order to project theskewer into the opening in the end of the shaft 2'. ing in the collar mand the skewer is provided near said end with a flange m which,

by contact with an internal flange m in the collar, preventslongitudinal movement of the skewer independently of the collar butpermits the skewer to rotate freely therein. (See Fig. 10.) By turningthe collar m so that the cam surfaces m and m are moved out ofengagement with each other the skewer can be retracted sufficiently tofree its opposite end from the recess in the shaftt'and can then beswung upward so as to permit of the removal of the cop therefrom.

While it is possible to start the winding of acop upon the springfingers 2" of the shaft '5,

excessive twist in the yarn first wound.

sents, approximately, thesame surface to the yarn as would the nose ofthe full sized cop.

In the base of the cone is is a transverse recess as shown in Fig. 5,and within this recess is a sliding bolt with an opening for thereception of the skewer m,a spring 70 being interposed between the innerend of said 1 bolt is and an adjusting screw plug 70 at the end of thetransverse opening in the cone, so that said bolt may always be pressedagainst the skewer with friction according to the requirements of theyarn and sufficient to prevent any accidental movement of the cone onthe skewer without, however, preventing the free out-ward movement ofsaid cone as the yarn is gradually wound between the same;

and the tapering nose B of the flier.

The spring fingers t" of the shaft 2' serve to positively clutch thecone 70 to said shaft until the winding operation has been well started,

and when the cone has been moved so far outward on the skewer as to befree from said spring fingers, the latter are engaged directly by theyarn and take such hold upon the cop as to insure the rotation of thesame within the flier at the same rate of speed as the shaft '5, while,at the same time, the yarn delivers readily from said fingersand passestherefrom onto the skewer as the cop grows in length.

The machine as shown in the drawings is adapted for the twistingtogether of two strands of yarn, each hank being mounted upon reels or:adapted to suitable hangers on the frame of the machine, the lowerhanger x being in the form of a lever having a fixed counterbalanceweight Y00 and an adjustable counterbalance weight 00 the latter beingcarried by a downwardly projecting short arm a of the lever so that byadjusting the weight on this arm the tension upon the hank can be veryaccurately regulated and the hank thus The end of the skewer m has abearsired lightness in the reel 00, therefore, I make the heads 41: ofthe reel of a commercial article known as chair seating, which iscomposed of three layers of veneering glued together, and the cross barsm I make of metal and provide each with a right hand screw thread on oneend, and a left hand thread upon theother end,and introduce them intocorrespondingly threaded openings in the heads of the reel, thuspreventing any possibility of their becoming loose, and at the same timeforming a thorough brace for the heads. (See Fig. 12.)

The center of each reel head is provided with a bush m of some malleablematerial held in place by an upsetting or riveting op- .eration similarto that performed on an eyelet. The layers or plies of each head of thereel are so disposed that the grain in one ply crosses that of theadjoining ply, so that end grain must be presented to the threads of theconnecting rods in at least one of the plies in each head and the properhold of said rods upon the heads is thus insured. Moreover, the threadedends of the rods serve to secure together the various plies at thepoints where said rods engage with the heads and any separation of theplies at the central portion of either head is prevented by reason ofthe eyelet form of the bushing. Each strand of yarn passes from its hankup to and over a guide roller 1?. on a lever 92 Fig. 7, attached to anarm n which is connected by a coiled spring 71. to a standard n on thefixed frame of the machine, the spring beingbent so as to permit the armn to project toward the end of the machine and thereby impart suchlifting tendency to the outer end of the arm and t0 the rollers 91. asto subject the strands to the desired degree of tension. In addition toits lifting tendency the spring n also acts by its torsion upon the armn and equalizing lever W, and in case the tension upon one of thestrands is through any cause increased, the guide roller 92 over whichit passes is thereby depressed and the opposite arm of the lever n withits .gnide roller is elevated correspondingly, and this increases thetension upon the strand which passes over it in practically the sameratio in which the tension on the first strand was increased, thusequalizing the tension on both strands and insuring an even twist. Amodification of this device is shown in Fig. 9 in which the lever n ishung to a tension spring a and is acted on by the ends of a spring nwhich tend to keep it in a mid position. From the rollern each strandpasses beneath a roller t carried by a lever 25' hung the hollow shaft fat the outer end of the flier,

thence around guide rollers 25 on the frame of the flier, thence aroundthe roller e on the traverse guide D, and thence to the nose of the copwhich is being wound, hence, as the flier rotates, the strands passingthrough the hollow shaft at the outer end of the same are twisted andthe twisted strands are wound into the form of a cob, the amount oftwist being dependent upon the relative speeds of rotation of the flierand cob, and this being determined by the relative speeds of the shaftsf and i which are regulated by the change gears before referred to.

' The swinging frame A has, beneath the bearing f, a notched segment 19with which engages a pawlp hung to a depending bracket on the undersideof a projection p on the main frame of the machine, as shown in Fig; 6,so that the frame A can be supported in such position as to hold thepulley a up into engagement with the driving belt (1 but as soon as thepawl is withdrawn from engagement with the segmental rack 19 the frame Aswings downward so as tocause a drop of the pulley a and sucha looseningof the belt a as will prevent it from driving said pulley, the latterdropping into contact with a plug 19 of wood or other frictionalmaterial mounted in the projection 19 and serving as a brake toimmediately arrest the movement of the pulley a In order to prevent thebelt from falling off the pulley a when in its slack state, and to guidethe same when running, jaws a are formed on the frame of the machine.The pawl 13 is connected by a rod 5 to the swinging frame .9 hung to thebracket 2? at the end of the machine so that by an outward pull uponthis frame the machine can be instantly stopped, and in order to providefor the stoppage of the machine when either of the strands becomebroken, said frame is provided with an opening through which, when themachine is in operation, plays a collar 3 on a rod 8 connected to adepending arm 3 on the traverse guide D, and having consequently, alongitudinal motion parallel with the axis of the flier.

The inner ends of the levers t which carry the guide rollers for thestrands of yarn are so arranged that when said levers are not supportedby the strands the inner ends of the levers will project in front of theopening in the frame 8' as shown by full lines in Fig. 7, and will, whenin such position, be struck by the collar .9 and cause the movement ofthe same to be transmitted to the swinging frame so as to pull the pawlp out of engagement with the rack 19 and thus permit the drop of theframe A and the stoppage of the machine, it being understood that whenthe rollers 15 are in engagementwith the strands of yarn andaresupported thereby, the inner ends of the lovers t are drawn away fromin front of the opening in the swinging frame 8' as shown by dottedlines in Fig. 7, and hence do not interfere with the free passage of thecollar 5 into said opening.

In order to provide for theautomatic stoppage of the machine when thefull cop has been wound I provide the cone is with a proj ecting hook towhich, when a cop of full length has been wound, and the cone reachesthe limit of its outward movement, catches the twisted strands as thelatter pass from the hollow shaft at the outer end of the flier to thefirst of the guide rolls t thereon, this hook being so constructed as tocutthe strands or simply so as to catch and hold the same so as to causethem to become broken by the pull of the cop upon them, the result ineither case being the stoppage of the machine through the medium of theautomatic stop motion which I have just described.

In cases wherethere are likely to be frequent changes in the extent oftwist imparted to the strands, I prefer to apply change gears to theshafts a and b so that one change of gear at this point will affect theentire machine, for it should be understood that in practice a largenumber of twisting and winding mechanisms will be mounted upon the sameframe and driven by the same shafts a and b. In this case I prefer todrive the pulleys a on the shafts f from belt wheels f on one of theshafts say the shaft (1, and pulleys i on the shafts i from belt wheelsi on the other shaft, so that any change in the speed of the shafts aand b will eifect a corresponding changein the speed of the shafts f andt'. This arrangement is represented in diagrammatic form in Fig. 8.
